if 2 cm on a map is 50 kms what is 8.5 cms on a map...how many kms ???
use a straightforward proportion
2 cm/50 km = 8.5 cm / x km
2x = 42.5
x = 21.25
8.5 cm on the map represent 21.25 km
To find out how many kilometers 8.5 cms on a map represents, we need to set up a proportion based on the given information.
The proportion is as follows:
2 cm on a map represents 50 km
x cm on a map represents the unknown number of km (which we want to find)
We can set up the proportion as:
2 cm / 50 km = 8.5 cm / x km
To solve for x, we can cross-multiply:
2 cm * x km = 8.5 cm * 50 km
To isolate x, we divide both sides of the equation by 2 cm:
x km = (8.5 cm * 50 km) / 2 cm
Now, we can simply calculate this expression to find the answer:
x km = 212.5 km
Therefore, 8.5 cms on the map represents 212.5 kilometers.
